The following requirements shall govern sanitary sewer improvements:
(a) Where an adequate public sanitary sewer system is reasonably accessible in the determination of the Planning Commission, public sanitary sewers shall be installed to serve all lots adequately, including lateral connections to the public system. Public sewer systems extensions shall meet the requirements of Ohio R.C. 3701.34 and regulations promulgated thereunder. Combinations of sanitary sewers and storm sewers shall be prohibited.
(b) Where a public sanitary sewer system is not reasonably accessible, the subdivider shall provide:
(1) A central treatment plant for the group, provided that such central treatment plant is installed in accordance with Ohio R.C. 3701.34 and regulations promulgated thereunder; or
(2) Lots may be served by individual disposal systems if the provisions of Section 1224.71(c) are met.
(c) (1) Where the installation of individual disposal systems is considered, the suitability of the soil for individual systems, the absorptive ability of the soil, surface drainage, ground water level and topography shall be the criteria for determining whether or not the installation of individual systems is permissible. Criteria shall be in accordance with the requirements of Ohio R.C. 3701.34 and regulations promulgated thereunder, when applicable.
(2) Each lot so served shall be of a size and shape to accommodate the necessary length of tile field at a safe distance from and at a lower elevation than the proposed building(s). Such lot size and shape shall conform to the requirements of the zoning district in which they are located. If no zoning is in effect, the standards set forth in Section 1224.47 of these regulations shall be met.
(3) At least one percolation test shall be made within each lot, shall be numbered, and its location shall be shown on the preliminary plat. All percolation tests shall be performed in accordance with the requirements of the Planning Commission and the City Board of Health.
(4) Where the installation of individual disposal units is considered and where the average natural ground slope exceeds ten percent, the installation of a step-up disposal system may be required subject to specifications by the City Board of Health.
